Every time I try "sudo apt-get update" it does a little then I get the following,

What release of Ubuntu are you running?
A complete output, including the repositories that worked, would also be helpful.

Red Flag: Those Utopic (14.10) repositories are past End Of Life and no longer supported. If you are really running 14.10, the recommended solution will be to install a supported release of Ubuntu. If you are running a different release of Ubuntu, then there is a smill bit of maintenance to do.

Red Flag: Looks like you are trying to mix Debian Sid and Debian Unstable and Ubuntu repositories. That's not supported, and it's an easy way to break your system quite terribly. If you tell us what you were trying to accomplish, we may be able to suggest a safer, supported way to accomplish it.
